My invention` comprises, more` specically, a The periphery of the 1basewasher 'I is provided waxer ofthe abovecharacter in whicha suitablewitha flaring skirt orange I4 having at one 50 support is provided withan uprising pin on ywhich point thereon a weighted p ojection I5 oi'hard- .the uprising hub of the rotary base washer is tenedor wearresisting material, which projection `loosely hung for limitedlateralmovement, the unbalances the base washer sufliciently to causebasewasher being weighted on its periphery, as, it, by centrifugalaction, to bring the projecfor instance, by` a `hardened orv wearresisting tion I5into 'Contact with the side wall 5 of the 55 supportwhen the rotative speed of the washer rises to a predetermined point.This contacting of the projection I5 with the side wall 5 causes therotative speed of the washer to be automatically reduced to a safelimit.

The washer supporting pin 6 may be adjusted laterally to and secured indifferent positions with respect to the side wall 5 of the support so asto increase or diminish the normal space between the washer and the saidside wall, to suit diierent yarn and speed conditions as will behereinafter more fully explained. This lateral adjustment of the pin andthereby the washer suspended therefrom is accomplished by providing thepin with a threaded portion I6 which extends through a hole I1 in thecrossbar 3, which hole is considerably larger in diameter than thediameter of the said threaded portion I6. Lock nuts I8 and I9 arethreaded on the portion I B above and below the crossbar 3, which nutsmay be tightened to secure the pin in its lateral adjustment withrespect to the side wall 5 of the support.

As the yarn passes from the tension device to and through the waxer tothe package being wound, the yarn will rotate the washer and the waxcake carried thereby. When the washer rises to a predetermined speed theweighted projection I5 will, because of centrifugal force on theunbalanced washer, be brought into contact with the side wail 5 of thesupport to automatically retard the washer.

The reason for the lateral adjustment of the pin 6 is to increase ordecrease the normal space between the weighted projection on theeccentrically weighted washer and the side wall of the support. Thiswill allow a greater or lesser degree of impact when the weightedprojection hits the side wall as the washer rises to a predeterminedspeed. When the upright pin B is permanently set, the centrifugallyrotated washer and the side wall, constituting the speed controllingmechanism, automatically compensate for different speeds of yarn.

From the above description it will be seen that I have produced a waxerhaving automatic centrifugally controlled means for retarding to agreater or lesser extent the free rotation of the washer and its waxcake to suit different requirements as hereinabove pointed out, and itwill also be seen that I have produced a waxing device which may beadjusted' to suit different yarn and speed conditions.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence I do notintend to be limited to the particular embodiment herein shown anddescribed, but

What I claim is:

1. In a yarn waxer, a support, a rotary eccentrically weighted washerand a wax cake carried thereby, the weighted side of the said washerbeing arranged, by centrifugal action, to be brought into contact withthe support for automatically retarding the washer.

2. In a yarn waxer, a support, ay rotary eccentrically weighted washerand a wax cake carried thereby, the weighted side of the said washerbeing arranged, by centrifugal action, to be brought into contact withthe support for automatically retarding the washer, and means forlaterally adjusting the position of the washer to suit diierent yarn andspeed conditions.

3. In a. yarn waxer, a support, an uprising pin,

a rotary eccentrically weighted washer loosely hung thereon and a waxcake carried by the washer, said washer being arranged, by centrifugalaction, to be brought into contact with the support for automaticallyretarding the Washer.

4. In a yarn waxer, a support, an uprising pin, a rotary eccentricallyweighted washer loosely hung thereon and a wax cake carried by thewasher, said washer being arranged, by centrifugal action, to be broughtinto contact with the support for automatically retarding the washer,and means for laterally adjusting the pin and thereby the washer to suitdifferent yam and speed conditions. A

5. In a yarn waxer, an uprising pin, a rotary washer having an uprisinghub loosely hung on said pin and a wax cake carried by the washer, saidwasher being arranged, by centrifugal action, to be brought into contactwith the support for automatically retardng the washer.

6. In a yarn waxer, an uprising pin, a rotary washer having an uprisinghub loosely hung on said pin and a wax cake carried by the washer, saidwasher being arranged, by centrifugal action, to be brought into contactwith the support for automatically retarding the washer, and means forlaterally adjusting the pin and thereby the washer to suit diierent yarnand speed conditions.

7. In a yarn waxer, a support, a rotary washer and a wax cake carriedthereby, said washer having centrifugally controlled means arranged tocontact with the support for automatically retarding the washer when itrises to a predetermined speed.

8. In a yarn waxer, a support, a rotary washer and a wax cake carriedthereby, said washer having centrifugally controlledmeans arranged tocontact with the support for automatically retarding the washer when itrises to a predetermined speed, and means for laterally adjusting theposition of the washer to suit diiferent yarn and speed conditions.

9. In a yarn waxer, a support, an uprising pin, a rotary washer looselyhung thereon and a wax cake carried by the washer, said washer havingcentrifugally controlled means arranged to contact with the support forautomatically retarding the washer when it rises to a predeterminedspeed.

10. In a yarn waxer, a support, an uprising pin, a rotary washer looselyhung thereon and a wax cake carried by the washer, said washer havingcentrifugally controlled means arranged to contact with the support forautomatically retarding the washer when it rises to a predeterminedspeed, and means for laterally adjusting the pin and thereby the washerto suit yarn and speed conditions.

11. In a yarn waxer, a support,- an uprising pin, a rotary washer havinga hub loosely hung on said pin and a wax cake carried by the washer,said washer having centritugally controlled means arranged to contactwithv the support for automatically retarding the washer when it risesto a predetermined speed.
